Does physics describe anything that can meaningfully be called “independent reality,” or is it merely operational? Most physicists implicitly favor an intermediate standpoint, which takes quantum physics into account, but which nevertheless strongly holds fast to quite strictly realistic ideas about apparently “obvious facts” concerning the macro-objects. Part 1 of this article, which is a survey of recent measurement theories, shows that, when made explicit, the standpoint in question cannot be upheld. Part 2 brings forward a proposal for making minimal (...) changes to this standpoint in such a way as to remove such objections. The “empirical reality” thus constructed is a notion that, to some extent,does ultimately refer to the human means of apprehension and of data processing. It nevertheless cannot be said that it reduces to a mere name just labelling a “set of recipes that never fail.” It is shown that our usual notion of macroscopic causality must be endowed with similar features.

Evidence suggests that psychedelics bring about their therapeutic outcomes in part through the subjective or qualitative effects they engender and how the individual interprets the resulting experiences. However, psychedelics are contraindicated for individuals who have been diagnosed with certain mental illnesses, on the grounds that these subjective effects may be disturbing or otherwise counter-therapeutic. Substantial resources are therefore currently being devoted to creating psychedelic substances that produce many of the same biological changes as psychedelics, but without their characteristic subjective effects. (...) In this article, we consider ethical issues arising from the prospect of such potential “nonsubjective” psychedelics. We are broadly supportive of efforts to produce such substances for both scientific and clinical reasons. However, we argue that such nonsubjective psychedelics should be reserved for those special cases in which the subjective effects of psychedelics are specifically contraindicated, whereas classic psychedelics that affect subjective experience should be considered the default and standard of care. After reviewing evidence regarding the subjective effects of psychedelics, we raise a number of ethical concerns around the prospect of withholding such typically positive, meaningful, and therapeutic experiences from most patients.

With regard to the notion of cause—or more generally of influence—the various methods of proof of Bell's theorem do not all have the same bearing. The differences between two of these methods are analyzed, with regard to both their conceptual basis and their conclusions. It is shown that both methods give valuable information but, not too surprisingly, the one that is based on the more detailed and specific definition of the concept of influences, and that makes use of the concept (...) of attribute, leads to conclusions that are also to some extent more specific than those following from the other method.

The idea is discussed according to which, in the Heisenberg picture, the operators correspond to the dynamic properties while the density matrix corresponds to our knowledge. A simple, soluble model is made use of in order to determine in what way this idea needs to be refined and what it then tells us about the relationship of reality and physics.

Various U.S. laws, such as the Clean Air Act and the Food Quality Protection Act, require additional protections for susceptible subpopulations who face greater environmental health risks. The main ethical rationale for providing these protections is to ensure that environmental health risks are distributed fairly. In this article, we (1) consider how several influential theories of justice deal with issues related to the distribution of environmental health risks; (2) show that these theories often fail to provide specific guidance concerning policy (...) choices; and (3) argue that an approach to public decision making known as accountability for reasonableness can complement theories of justice in establishing acceptable environmental health risks for the general population and susceptible subpopulations. Since accountability for reasonableness focuses on the fairness of the decision-making process, not the outcome, it does not guarantee that susceptible subpopulations will receive a maximum level of protection, regardless of costs or other morally relevant considerations.

Childhood obesity has become a public health epidemic, and currently a battle exists over how to frame and address this problem. This paper explores how public policy approaches can be employed to address obesity. We present the argument that obesity should be viewed as the consequence of a “toxic environment” rather than the result of the population failing to take enough “personal responsibility.” In order to make progress in decreasing the prevalence of obesity, we must shift our view of obesity (...) away from the medical model to a public health model . At the same time, we must be sensitive to the problem of weight bias.Potential obstacles to taking a public policy approach are identified, as well as suggestions on how to overcome them. (shrink)

A brief statement of medieval linguistic analysis as found chiefly in the works of Thomas Aquinas. A thin survey of contemporary analysis is offered in order to contrast the purported acceptance of analysis as the end of philosophy with Thomas' use of analysis as method. Unfortunately, most of the constructive work in language analysis during the past ten years is not considered. The brevity of the text precludes persuasive treatment; yet the book succeeds in its expressed purpose of sketching some (...) chief differences between the medieval and contemporary approaches in the hope that the confrontation of these currents will bring to the fore the analytic work of Aquinas himself.--D. P. B. (shrink)

Directed to the non-philosopher, this is an attempt to sketch briefly a public philosophy for contemporary America. It attacks the "enfeebling naturalism" of Dewey and espouses the right of suffrage as the most fundamental right of man.--D. P. B.

Marsh borrows Richard McKeon's methodological notion of the "problematic" approach to intellectual history. Concentrating on their dialectical character, English criticism from 1650-1800 is explored in the writings of the third Earl of Shaftesbury, Mark Akenside, David Hartley, and James Harris.—D. J. B.

Along with a line by line translation and interpretation of the fragments, are four essays: "Parmenides' Concept of Being," "Aletheia and Doxa," "The World of Appearance Described in the Doxa," and "Parmenides in the Ancient Philosophical Tradition." Parmenides did not understand the logical connection between time and process: undifferentiated Being is without process but, curiously enough, possesses temporal duration. The philosophical tradition wrongly interpreted the Doxa as Parmenides' cosmogony. In short, this important book is a splendid example of painstaking scholarship. (...) The footnotes and references to other critical studies of Parmenides are comprehensive.—D. J. B. (shrink)

This book gives the beginning student one more passable text to chose for an introductory survey of the history of Western philosophy. Surveys of this sort usually contain some questionable assertions—e.g., referring to Aquinas' proof of God from motion, Stumpf states: "Potentiality means the absence of something and is therefore nothing...". But Stumpf writes clearly enough and includes a useful bibliography.—D. J. B.

Writing in Elizabethan English and Renaissance Latin, Stapleton was one of the leading controversialists in the Catholic Counter Reformation of the sixteenth century. Two areas of specific disagreement were the problem of justification and church government but Stapleton could indulge in the usual bitter polemics of the period by emphasizing Protestant abuses and minimizing similar conditions on the Catholic side. Father O'Connell writes well and is in control of the sources.—D. J. B.

Arguing from a sort of reasonable Protestant ethic, Henry offers a worthwhile and sometimes quite practical analysis of a Christian social ideal. In Henry's approach, no "prattling about love" can take the place of justice when the latter is what is needed.—D. J. B.

The authors use the term “principlism” to refer to the practice of using “principles” to replace both moral theory and particular moral rules and ideals in dealing with the moral problems that arise in medical practice. The authors argue that these “principles” do not function as claimed, and that their use is misleading both practically and theoretically. The “principles” are in fact not guides to action, but rather they are merely names for a collection of sometimes superficially related matters for (...) consideration when dealing with a moral problem. The “principles” lack any systematic relationship to each other, and they often conflict with each other. These conflicts are unresolvable, since there is no unified moral theory from which they are all derived. For comparison the authors sketch the advantages of using a unified moral theory. (shrink)

ABSTRACTTo build a process model of the understanding of conditionals we extract a common core of three semantics of if-then sentences: the conditional event interpretation in the coherencebased probability logic, the discourse processingtheory of Hans Kamp, and the game-theoretical approach of Jaakko Hintikka. The empirical part reports three experiments in which each participant assessed the probability of 52 if-then sentencesin a truth table task. Each experiment included a second task: An n-back task relating the interpretation of conditionals to working memory, (...) a Bayesian bookbag and poker chip task relating the interpretation of conditionals to probability updating, and a probabilistic modus ponens task relating the interpretation of conditionals to a classical inference task. Data analysis shows that the way in which the conditionals are interpreted correlates with each of the supplementary tasks. The results are discussed within the process model proposed in the introduction. (shrink)

We apply an online optimization process based on machine learning to the production of Bose-Einstein condensates. BEC is typically created with an exponential evaporation ramp that is optimal for ergodic dynamics with two-body s-wave interactions and no other loss rates, but likely sub-optimal for real experiments. Through repeated machine-controlled scientific experimentation and observations our ’learner’ discovers an optimal evaporation ramp for BEC production. In contrast to previous work, our learner uses a Gaussian process to develop a statistical model of the (...) relationship between the parameters it controls and the quality of the BEC produced. We demonstrate that the Gaussian process machine learner is able to discover a ramp that produces high quality BECs in 10 times fewer iterations than a previously used online optimization technique. Furthermore, we show the internal model developed can be used to determine which parameters are essential in BEC creation and which are unimportant, providing insight into the optimization process of the system.

A series of amorphous essays, including one by S. Radhakrishnan, so general in content as to be of dubious value. For those who have a developed sense of whimsey, there are a few striking aphorisms to be garnered here and there in the volume.—D. J. B.

As indicated by the title, this book contains seven very scholarly essays on Jewish life and thought in the 19th century. Of particular interest to philosophers is Prof. Emil L. Fackenheim's essay, "Samuel Hirsch and Hegel: A Study of Hirsch's Religionsphilosophie der Juden." In this essay, Fackenheim's masterful knowledge of Hegel is clearly visible. The thirty page essay contains a profound awareness of the theological problems inherent in Hegel's philosophy of religion as well as an awareness of how these problems (...) were explicitly engendered by Hegel's metaphysics. As an introduction to some of Hegel's basic themes, Fackenheim has provided an invaluable, if, unfortunately, all too brief, introduction.—D. J. B. (shrink)

Though the individual chapters appeared as essays in various journals, their cogency and urbane scholarship make them particularly noteworthy in book form. In the chapter "Social Problems in the Early Church" Ehrhardt suggests an important methodological principle: the history of theological development cannot ignore the social conditions of the little people who accepted the Christian message. The most demanding chapter of the book, "Creatio ex Nihilo," is also the most unsatisfactory. Ehrhardt has command of the historical sources, but his treatment (...) of the relevant philosophical problems is less than clear. It need only be added that the first chapter, "The Theology of New Testament Criticism" is a devastating attack on unenlightened faith.—D. J. B. (shrink)

This is Volume IV in the Evangelical Commentary on the Bible. As one might expect, the authors avoid novelty—which does not detract from the value of their work. A lengthy introduction provides a lucid summary of contemporary scholarship on the influence, distinctive features, background, problems, and text of the Fourth Gospel. The authors incline to the view that the Gospel is at least the "witness" of the Apostle John though the actual writing may have been done by a later "John (...) the Presbyter or an unnamed disciple." Each page of the commentary has four divisions: 1) text, 2) exegesis, 3) exposition, 4) footnotes. The exposition is intended to relate John's message to contemporary life and is, therefore, a useful preaching aid.—D. J. B. (shrink)

This is a collection of Professor De Koninck's incidental writings, treating of such topics as "Contre l'antisémitisme," "Pie IX sur l'ignorance invincible de la vraie religion," "Ce qui est à César," et al. Whatever the intrinsic merits of these essays, they will be of interest to anyone who has followed the late Professor De Koninck's career as a scholar, teacher, and dedicated Catholic layman.—D. J. B.

After an exceedingly short treatment of six theories of tragedy, the author concludes that while each has emphasized a necessary component of the tragic, none has really come to grips with its basic "paradox": the fact that while the art of tragedy attempts to explain the mystery of human suffering, such an attempt is doomed to failure.--D. C. B.

This, the third volume in The Pelican History of the Church, offers an extremely perspicacious view of the entire period. While there were nationalistic, economic, and political interests responsible for the Reformation and while there was no one, simple religious motivation, underlying all of these causes was a profound dissatisfaction with the moral and religious tone of late medieval society. However haltingly and destructively the Reformation proceeded, it is evident that the result was a general strengthening of authentic religious life (...) in both Protestant and Catholic countries. And where the state assumed some of the secular functions of the medieval Church this seemed to eventually benefit both Church and State. However, Chadwick does not gloss over grosser aspects of the period: the so-called wars of religion, the endless and destructive polemics between churches, and the ruthless confiscation of ecclesiastical property. If greedy lords helped free the Church from the mammon of iniquity, this was accompanied by cultural and artistic losses with no improvement in the lot of the poor country cleric despite the reduced status of the wealthy bishop or abbot. Chadwick is particularly good in his descriptions of the relationship of the political to the religious. But what is of special interest are the sometimes bewildered and reactionary responses of the little Christian to the dramatic events of the time.—D. J. B. (shrink)

Hardly a systematic anthropology, Heschel's book, which has at times an almost devotional flavor, contains enough insights, aphorisms, moral intuitions, and wise asides to be worth reading.—D. J. B.

The progression of research and scholarly inquiry does not occur in isolation and is wholly dependent on accurate reporting of methods and results, and successful replication of prior work. Without mechanisms to correct the literature, much time and money is wasted on research based on a crumbling foundation. These guidelines serve to outline the respective responsibilities of researchers, institutions, agencies, and publishers or editors in maintaining the integrity of the research record. Delineating these complementary roles and proposing solutions for common (...) barriers provide a foundation for best practices. (shrink)

In vitro fertilization using donated oocytes has proven to be an effective treatment option for many prospective parents struggling with infertility, and the usage of donated oocytes in assisted reproduction has increased markedly since the technique was first successfully used in 1984. Data published by the Centers for Disease Control and Prevention on the use of assisted reproductive technologies in the United States indicate that approximately 12% of all ART cycles in the country now use donated oocytes. The increased use (...) of oocyte donation in the United States has prompted discussion regarding risks associated with the process and how best to ensure the safety of oocyte donors.Physical risks associated with oocyte donation include bleeding, infection, ovarian hyperstimulation syndrome and a potential, although unconfirmed, increased risk of developing various forms of cancer, such as uterine, colon, breast, ovarian, and endometrial cancers.
